These devices allow you to load or unload the system, simply and quickly.
once these loading or unloading operations are completed, a cap with gasket is available. Assemble the cap on the charge connection to prevent any possible loss of refrigerant.
The device can also be closed using a blind union (article 31001) by interposing the truN.C.ated conical copper gasket with tang (article 31517).
The mechanism housing, provided in the charging connections, is made according to the ARI STANDARD 720: 1997 standard.
By screwing the mechanism inside the charging connection (according to the appropriate tightening torque), the passage of the refrigerant in the charging or discharging operations is obtained by simply operating the pin of the mechanism itself.
